Me and my husband saw.. baby was making bad faces and as if he is crying in womb.. why baby cry in womb i am wondering.. i have read on google somewhere that if baby cry he is not happy. And doc said.. baby's rember past life.. and accordingly they react. I dont know exact reason .. can anyone know.. coz in my whole pregnancy i was not so happy.. is tat a reason?
